REQUEST FOR MORE INFORMATION: STORMWATER MANAGEMENT PLAN
Dear Mr. Poole:
On May 21, 2009, the Division of Water Quality (DWQ) issued a 401 Water Quality Certification to
permanently impact 192 linear feet of perennial stream, 9,770 square feet of Zone 2 Neuse River
basin riparian buffer, and 15,004 square feet of Zone 1 Neuse River basin riparian buffer to facilitate
development of the Caterpillar Core PDC site. In order to meet Conditions 6 and 7 of the 401
Certification for this project, a stormwater management plan prepared by your consulting engineer
McKim & Creed, dated August 12, 2009, was received by the DWQ on August 13, 2009.
The DWQ has determined that this stormwater management plan was incomplete as discussed below.
Additional Information Requested:
1. Please provide a BMP Supplement Form for each proposed best management practice that
will be used on the site (including both worksheets, Design Summary and Required Items
Checklist), as well as all of the required items. The BMP Supplement Forms are available on
the DWQ web site at: http://h2o.enr.state.nc.us/su/bmp forms htm. The DWQ will conduct a
detailed review of the BMP designs after this information has been submitted.
2. The level spreader that is proposed downslope of BMP #1 must be relocated to an area that
has appropriate slope and topography per Chapter 8 of the BMP Manual.
Condition 7 states: "All areas on the site that shall be utilized for equipment testing shall be
shown clearly on the plans... In addition, the testing processes themselves and their impacts
on the natural land surface shall be described in detail. Any areas that will be left
undisturbed on an ongoing basis shall be equipped with appropriate Sediment and Erosion
Control measures..." Although the testing area has been shown clearly on the plans, the
remainder of this condition does not appear to have been met. Please provide the requested
description as well as plan details for the proposed sediment and erosion control measures.
